The present application claims priority to Japanese Patent ApplicationJP 2006-015558 filed in the Japanese Patent Office on Jan. 24, 2006, theentire contents of which is being incorporated herein by reference.

BACKGROUND

The present disclosure relates to a separator and a battery and, moreparticularly, to a microporous separator and a battery using such aseparator.

Owing to the development of a recent portable electronic apparatustechnique, electronic apparatuses such as cellular phones,notebook-sized computers, and the like are appreciated as a basictechnique which supports an advanced information society. Studies anddevelopment regarding a technique for realizing advanced functions ofthose electronic apparatuses are vigorously being progressed. Electricpower consumption of those electronic apparatuses is also increasing inproportion. On the contrary, it is requested that those electronicapparatuses can be driven for a long time and it is inevitably requestedto realize high energy density of a secondary battery serving as adriving power source.

From viewpoints of an occupied volume, a mass, and the like of a batterywhich is built in the electronic apparatus, the larger energy density ofthe battery, the better. At present, lithium ion secondary batteries arebuilt in most of the apparatuses because they have excellent energydensity.

Generally, in the lithium ion secondary battery, lithium cobalt acid isused for a cathode, a carbon material is used for an anode, and anoperating voltage is set to a value within a range from 2.5 to 4.2 V. Ina single battery, a terminal voltage can be raised to 4.2V owing to anexcellent electrochemical stability of a non-aqueous electrolytematerial, a separator, and the like.

On the other hand, in the lithium ion secondary battery in the relatedart which operates at the maximum voltage of 4.2V, a cathode activematerial such as lithium cobalt acid or the like which is used for thecathode merely uses a capacitance of about 60% of its theoreticalcapacitance and a residual capacitance can be utilized in principle byfurther raising a charge voltage. Actually, it has been known that thehigh energy density can be realized by setting the voltage upon chargingto 4.25V or more (for example, refer to a pamphlet of InternationalPublication No. WO03/019713).

In such a lithium ion secondary battery, although the battery has beendesigned so as to assure sufficient safety under the ordinary usingconditions, in order to cope with the realization of the recent highcapacitance, higher safety is requested.

In a lithium ion secondary battery having a winded laminate structure,in order to realize higher safety, there has been proposed a techniqueto use a structure in which cathode/anode collector exposed portions aremade to face cathode/anode outermost peripheral portions by a length ofone circumference or more (for example, refer to JP-A-1996 (Heisei8)-153542. According to such a lithium ion secondary battery, even if itis erroneously used, a sudden temperature increase of the battery can besuppressed by an inner short-circuit due to a contact of metals whoseelectric resistances are sufficiently small. The lithium ion secondarybattery having such a structure has already been put into practical useand it has been confirmed that the excellent effect is obtained.

SUMMARY

However, in the case of the battery whose charge voltage has been set toa value over 4.2V, since a degree of risk that is caused by theerroneous using method increases more than that in the battery in therelated art, it is necessary to further improve the safety. From aviewpoint of battery characteristics, it is also important to preventload characteristics from deteriorating in association with theimprovement of the safety.

In the battery whose charge voltage has been set to a value over 4.2V,therefore, it is desirable to provide a separator which can realizeexcellent safety without causing a deterioration in load characteristicsand to provide a battery using such a separator.

DETAILED DESCRIPTION (1) First Embodiment (1-1) Construction ofSecondary Battery

FIG. 1 is a cross sectional view showing an example of a construction ofa secondary battery according to the first embodiment. This secondarybattery is what is called a lithium ion secondary battery in whichlithium (Li) is used as an electrode reactive substance and a capacitorof an anode is expressed by a capacitive component due to dope anddedope of lithium. This battery is what is called a cylindrical type anda winded electrode member 20 around which a pair of belt-shaped cathode21 and a belt-shaped anode 22 have been wound through a separator 23 isprovided in an almost hollow cylindrical battery can 11. An electrolyticsolution as a liquid electrolyte is impregnated in the separator 23. Thebattery can 11 is made of, for example, iron (Fe) plated with nickel(Ni). One end portion of the battery can 11 is closed and the other endportion is open. A pair of insulating plates 12 and 13 are respectivelyarranged perpendicularly to a wound peripheral surface so as to sandwichthe winded electrode member 20.

A battery cap 14 and a relief valve mechanism 15 and athermally-sensitive resistive element (PTC element: Positive TemperatureCoefficient element) 16 provided in the battery cap 14 are caulkedthrough a gasket 17 and attached to the open end portion of the batterycan 11. The inside of the battery can 11 is sealed. The battery cap 14is made of for example, a material similar to that of the battery can11. The relief valve mechanism 15 is electrically connected to thebattery cap 14 through the PTC element 16. When an inner pressure of thebattery rises to a predetermined value or more due to an innershort-circuit, heating from the outside, or the like, a disk plate 15Ais turned round, thereby disconnecting the electrical connection betweenthe battery cap 14 and the winded electrode member 20. When atemperature rises, a current is limited due to an increase in resistancevalue of the PTC element 16 and abnormal heat generation by the largecurrent is prevented. For example, the PTC element 16 operates at atemperature of 120° C. or higher. The gasket 17 is made of, for example,an insulating material and its surface is coated with asphalt.

The winded electrode member 20 is wound around, for example, a centerpin 24 as a center. A cathode lead 25 made of aluminum (Al) or the likeis connected to the cathode 21 of the winded electrode member 20. Ananode lead 26 made of nickel or the like is connected to the anode 22.The cathode lead 25 is welded to the relief valve mechanism 15, so thatit is electrically connected to the battery cap 14. The anode lead 26 iswelded and electrically connected to the battery can 11.

Althoughnot shown, the cathode active material layer 21B may be provided foronly one surface of the cathode collector 21A. The cathode collector 21Ais made of, for example, a metal foil such as an aluminum foil or thelike.

As a cathode material which can dope and dedope lithium, inorganiccompounds such as MnO₂, V₂O₅, V₆O₁₃, NiS, MoS, and the like which do notcontain lithium can be also mentioned besides those materials.

(Anode)

The anode 22 has a structure in which, for example, anode activematerial layers 22B are provided for both surfaces of an anode collector22A having a pair of surfaces which face each other. Although not shown,the anode active material layer 22B may be provided for only one surfaceof the anode collector 22A. The anode collector 22A is made of, forexample, a metal foil such as a copper foil or the like.

As an anode active material, the anode active material layer 22B is madeby containing one, two, or more kinds selected from the anode materialswhich can dope and dedope lithium. The anode active material layer 22Bis made by containing a binder similar to that of the cathode activematerial layer 21B as necessary.

In this secondary battery, an electrochemical equivalent of an anodematerial which can dope and dedope lithium is larger than that of thecathode 21 and a lithium metal is not precipitated into the anode 22during the charging.

In this secondary battery, an open circuit voltage (that is, batteryvoltage) upon full charging is set so as to lie within a range from4.25V or more to 4.60V, both inclusive or a range from 4.35V to 4.60V,both inclusive. Therefore, even in the case of the same cathode activematerial, since an emission amount of lithium per unit mass is largerthan that of the battery in which the open circuit voltage upon fullcharging is equal to 4.20V, an amount of the cathode active material andthat of the anode active material are adjusted in accordance with theemission amounts of lithium. Thus, the high energy density can beobtained.

As an anode material which can dope and dedope lithium, for example, acarbon material such as non-easy-graphitizable carbon i.e. hard carbon,easy-graphitizable carbon i.e. soft carbon, graphite, pyrolytic carbonclass, coke class, glassy carbon class, organic high molecular compoundbaked material, carbon fiber, activated charcoal, or the like can bementioned. Among them, there is a pitch coke, a needle coke, a petroleumcoke, or the like as a coke class. The organic high molecular compoundbaked material denotes a material obtained by baking a high molecularmaterial such as phenol resin, fran resin, or the like at a propertemperature and carbonating it. A part of those materials are classifiedinto non-easy-graphitizable carbon i.e. hard carbon, oreasy-graphitizable carbon i.e. soft carbon. Polyacetylene, polypyrrole,or the like can be mentioned as a high molecular material. Those carbonmaterials are preferable because a change in crystal structure which iscaused upon charging or discharging is very small, a highcharge/discharge capacitance can be obtained, and good cyclecharacteristics can be obtained. Particularly, the graphite ispreferable because the electrochemical equivalent is large and the highenergy density can be obtained. The non-easy-graphitizable carbon i.e.hard carbon, is preferable because excellent characteristics can beobtained. Further, a material whose charge/discharge potential is low,specifically speaking, a material whose charge/discharge potential isclose to that of the lithium metal is preferable because the high energydensity of the battery can be easily realized.

As an anode material which can dope and dedope lithium, a material whichcan dope and dedope lithium and contains at least one kind selected froma metal element and a semimetal element as a component element can bealso mentioned. By using such a material, the high energy density can beobtained. Particularly, if it is used together with the carbon material,since the high energy density can be obtained and excellent cyclecharacteristics can be obtained, it is more preferable. Such an anodematerial may be a sole element of the metal element or the semimetalelement, an alloy of them, or a compound of them. A material containinga phase or phases of one, two, or more kinds of them in at least a partof it. In the embodiment, in addition to an alloy containing two or morekinds of metal elements, an alloy containing one or more kinds of metalelements and one or more kinds of semimetal elements is alsoincorporated. The material may also contain a non-metal element. As itstexture, there is a solid solution, an eutectic (eutectic mixture), anintermetallic compound, or a texture in which two or more kinds of themcoexist.

As such a metal element or semimetal element constructing the anodematerial, for example, magnesium, boron, aluminum, gallium (Ga), indium(In), silicon (Si), germanium (Ge), tin, lead (Pb), bismuth (Bi),cadmium (Cd), silver (Ag), zinc, hafnium (Hf), zirconium, yttrium (Y),palladium (Pd), or platinum (Pt) can be mentioned. They may becrystalline or amorphous.

Among them, as an anode material, a material containing a metal elementor a semimetal element of the 4B group in the short period type periodictable as a component element is preferable. A material containing atleast either silicon or tin as a component element is particularlypreferable. This is because according to silicon and tin, an ability ofdoping and dedoping lithium is high and the high energy density can beobtained.

As an alloy of tin, for example, an alloy containing at least one kindselected from a group including silicon, nickel, copper, iron, cobalt,manganese, zinc, indium, silver, titanium (Ti), germanium, bismuth,antimony (Sb), and chromium as a second component element other than tincan be mentioned. As an alloy of silicon, for example, an alloycontaining at least one kind selected from a group including tin,nickel, copper, iron, cobalt, manganese, zinc, indium, silver, titanium,germanium, bismuth, antimony, and chromium as a second component elementother than silicon can be mentioned.

As a compound of tin or a compound of silicon, for example, a compoundcontaining oxygen (O) or carbon (C) can be mentioned. In addition to tinor silicon, the foregoing second component element may be contained.

As an anode material which can dope and dedope lithium, further, anothermetal compound or a high molecular material can be mentioned. As anothermetal compound, an oxide such as MnO₂, V₂O₅, V₆O₁₃, or the like, asulfide such as NiS, MoS, or the like, or a lithium nitride such as LiN₃or the like can be mentioned. As a high molecular material,polyacetylene, polyaniline, polypyrrole, or the like can be mentioned.

(Separator)

The separator 23 has: a base material layer 23A; and a surface layer 23Bprovided on the surface of the base material layer 23A on the side whichfaces the cathode 21 or surface layers 23B provided on both surfaces ofthe base material layer 23A. In FIG. 2, a case where the surface layers23B are provided on both surfaces of the base material layer 23A isillustrated.

It is preferable that a thickness of separator 23 lies within a rangefrom 10 μm or more to 20 μm or less. This is because if the thickness issmall, there is a case where a short-circuit occurs, and if thethickness is large, an ion conductivity deteriorates and a volumecapacitance decreases. It is preferable that air permeability of theseparator 23 lies within a range from 100 [sec/100 ml] or more to 600[sec/100 ml] or less. This is because if the air permeability is low,there is a case where the short-circuit occurs, and if the airpermeability is high, the ion conductivity deteriorates. Further, it ispreferable that a porosity of the separator 23 lies within a range from30% or more to 60% or less. This is because if the porosity is small,the ion conductivity deteriorates, and if the porosity is large, thereis a case where the short-circuit occurs. In addition, it is preferablethat a piercing strength of the separator 23 is equal to or larger than100 gf. This is because when the piercing strength is too small, theshort-circuit could occur. It is also preferable that the piercingstrength of the separator 23 is equal to or smaller than 800 gf. This isbecause when the piercing strength is too large, the ion conductivitybecomes too low. It is more preferable that the piercing strength issmaller than 600 gf.

The base material layer 23A is a microporous membrane made of, forexample, polyolefin. As polyolefin constructing the microporousmembrane, for example, polypropylene or polyethylene can be used. Themicroporous membrane made of polyolefin is preferable because it has anexcellent short-circuit preventing effect and the improvement of thebattery safety due to a shut-down effect can be realized. Particularly,polyethylene is preferable as a material constructing the base materiallayer 23A because the shut-down effect can be obtained within a rangefrom 100° C. or more to 160° C. or less and it has an excellentelectrochemical stability. Polypropylene is also preferable. As anothermaterial, it can be used by being copolymerized with polyethylene orpolypropylene or by being blended therewith so long as it is a resinhaving a chemical stability.

The surface layer 23B is made by containing at least one kind selectedfrom a group including, for example, polyvinylidene fluoride,polytetrafluoro ethylene, polypropylene, and aramid. Thus, the chemicalstability is improved and the occurrence of the small short-circuit issuppressed. The surface layer 23B on the side which faces the cathode 21and the surface layer 23B on the side which faces the anode 22 are notlimited to the same material but they may be made of differentmaterials.

The base material layer 23A and the surface layer 23B have different airpermeability values. It is preferable that the air permeability of thebase material layer 23A lies within a range from 15 [sec/100 ml] or moreto 600 [sec/100 ml] or less. This is because if the air permeability isless than 15 [sec/100 ml], there is a case where the short-circuitoccurs. If the air permeability exceeds 600 [sec/100 ml], the loadcharacteristics deteriorate.

It is preferable that the air permeability of the surface layer 23B lieswithin a range from 45 [sec/100 ml] or more to 600 [sec/100 ml] or less.This is because if the air permeability is less than 45 [sec/100 ml],there is a case where the short-circuit occurs. If the air permeabilityexceeds 600 [sec/100 ml], the load characteristics deteriorate.

The separator 23 has the film thickness of 10 μm or more and 20 μm orless. When the film thickness of the separator is expressed as 10x μmusing factor x wherein 1≦x≦2, and the piercing strength is 150x gf ormore, it is preferable that the air permeability of at least one layerof microporous membranes constructing each layer of the separator, forexample, the base material layer 23A is equal to or larger than 10% ofthat of the whole separator. In other words, the separator 23 has thefilm thickness of 10x μm and the piercing strength of 150x gf or morewherein 1≦x≦2, and the air permeability of one layer of a plurality ofthe microporous membranes is equal to or larger than 10% of that of thewhole separator. If the air permeability is less than 10%, the safetydeteriorates.

When the film thickness of the separator is expressed as 10x μm usingfactor x wherein 1≦x≦2, and the piercing strength is 150x gf or less, itis preferable that the air permeability of at least one layer ofmicroporous membranes constructing each layer of the separator, forexample, the base material layer 23A is equal to or larger than 35% ofthat of the whole separator. In other words, the separator 23 has thefilm thickness of 10x μm and the piercing strength of 150x gf or lesswherein 1≦x≦2, and the air permeability of one layer of a plurality ofthe microporous membranes is equal to or larger than 35% of that of thewhole separator. If the air permeability is less than 35%, the safetydeteriorates.

It is preferable that a melting point of a material constructing thebase material layer 23A is lower than that of the surface layers 23B.Since the melting points differ as mentioned above, for example, in thecase where a large current flows in the battery and heat is generatedfrom the battery, the base material layer 23A is softened by the heatgeneration, the shut-down occurs, and the shape of the separator 23 canbe maintained by the surface layers 23B.

It is preferable that the thickness of material layer 23A lies within arange from 4.9 μm or more to 20 μm or less. If the thickness is lessthan 4.9 μm, the suppressing effect of the occurrence of the smallshort-circuit decreases. If the thickness exceeds 20 μm, the ionconductivity deteriorates and the volume capacitance decreases.

It is preferable that the thickness of surface layer 23B on the sidewhich faces the cathode 21 lies within a range from 0.1 μm or more to 10μm or less. If the thickness is less than 0.1 μm, the suppressing effectof the occurrence of the small short-circuit decreases. If the thicknessexceeds 10 μm, the ion conductivity deteriorates and the volumecapacitance decreases.

It is preferable that the thickness of surface layer 23B on the sidewhich faces the anode 22 lies within a range from 0.1 μm or more to 10μm or less. If the thickness is less than 0.1 μm, the suppressing effectof the occurrence of the small short-circuit decreases. If the thicknessexceeds 10 μm, the ion conductivity deteriorates and the volumecapacitance decreases.

(Electrolyte)

An electrolytic solution as a liquid electrolyte contains a solvent andan electrolytic salt dissolved into the solvent. Cyclic carbonic estersuch as ethylene carbonate, propylene carbonate, or the like can be usedas a solvent. It is preferable that either ethylene carbonate orpropylene carbonate or, particularly, both of them are mixed and used.This is because the cycle characteristics can be improved.

As a solvent, it is preferable to mix and use chain-like carbonic estersuch as diethyl carbonate, dimethyl carbonate, ethylmethyl carbonate,methylpropyl carbonate, or the like in addition to those cyclic carbonicester. This is because the high ion conductivity can be obtained.

Further, as a solvent, it is preferable to contain 2,4-difluoroanisoleor vinylene carbonate. This is because in the case of2,4-difluoroanisole, the discharge capacitance can be improved and inthe case of vinylene carbonate, the cycle characteristics can beimproved. Therefore, if they are mixed and used, since the dischargecapacitance and the cycle characteristics can be improved, it ispreferable.

As other solvents, the following materials can be mentioned: butylenecarbonate, γ-butyrolactone, γ-valerolactone, 1,2-dimethoxy ethane,tetrahydrofuran, 2-methyl tetrahydrofuran, 1,3-dioxorane,4-methyl-1,3-dioxorane, methyl acetate, methyl propionate, acetonitrile,glutaronitrile, adiponitrile, methoxy acetonitrile, 3-methoxypropylonitrile, N,N-dimethyl formamide, N-methylpyrrolidinone, N-methyloxazolidinone, N,N-dimethyl imidazolidinone, nitromethane, nitroethane,sulfolan, dimethyl sulfoxide, trimethyl phosphate, and the like.

There is also a case where a compound in which hydrogen in at least apart of those non-aqueous solvents has been replaced by fluorine ispreferable because there is a case where the reversibility of theelectrode reaction can be improved in dependence on the kind ofelectrode which is combined.

As an electrolytic salt, for example, a lithium salt can be mentioned.One kind can be solely used or two or more kinds can be also mixed andused. As a lithium salt, LiPF₆, LiBF₄, LiAsF₆, LiClO₄, LiB(C₆H₅)₄,LiCH₃SO₃, LiCF₃SO₃, LiN(SO₂CF₃)₂, LiC(SO₂CF₃)₃, LiAlCl₄, LiSiF₆, LiCl,difluoro [oxolato-O,O′] lithium boric acid, lithium bisoxalate borate,LiBr, or the like can be mentioned.

(1-2) Manufacturing Method of Secondary Battery

An example of a manufacturing method of the secondary battery accordingto the first embodiment is described below.

First, the cathode mixture is adjusted, for example, by mixing, thecathode active material, conductive material, and binder, the cathodemixture is dispersed into the solvent such as N-methyl-2-pyrolidone orthe like, thereby forming the paste-like cathode mixture slurry.Subsequently, the cathode collector 21A is coated with the cathodemixture slurry, the solvent is dried, thereafter, the obtained collectoris compression-molded by a roll pressing machine or the like, and thecathode active material layer 21B is formed. Thus, the cathode 21 isobtained.

For example, the anode active material and binder are mixed and theanode mixture is adjusted. This anode mixture is dispersed into thesolvent such as N-methyl-2-pyrolidone or the like, thereby forming thepaste-like anode mixture slurry. Subsequently, the anode collector 22Ais coated with the anode mixture slurry, the solvent is dried, andthereafter, the obtained collector is compression-molded by the rollpressing machine or the like, thereby forming the anode active materiallayer 22B. Thus, the anode 22 is obtained.

Subsequently, the cathode lead 25 is attached to the cathode collector21A by welding or the like and the anode lead 26 is attached to theanode collector 22A by welding or the like. Thereafter, the cathode 21and the anode 22 are wound through the separator 23, a front end portionof the cathode lead 25 is welded to the relief valve mechanism 15, afront end portion of the anode lead 26 is welded to the battery can 11,and the wound cathode 21 and anode 22 are sandwiched by the pair ofinsulating plates 12 and 13 and enclosed in the battery can 11. Afterthe cathode 21 and the anode 22 were enclosed in the battery can 11, theelectrolytic solution is injected into the battery can 11 and dippedinto the separator 23. Thereafter, the battery cap 14, relief valvemechanism 15, and PTC element 16 are caulked and fixed to the open endportion of the battery can 11 through the gasket 17. Thus, the secondarybattery shown in FIG. 1 is obtained.

In the secondary battery, when the charge is performed, lithium ions arededoped from the cathode active material layer 21B. Through theelectrolytic solution, the lithium ions are doped into the anodematerial which can dope and dedope lithium contained in the anode activematerial layer 22B. Subsequently, when the discharge is performed, thelithium ions doped in the anode material which can dope and dedopelithium in the anode active material layer 22B are dedoped and dopedinto the cathode active material layer 21B through the electrolyticsolution. Since the separator 23 has the construction mentioned above,the chemical stability is improved. Even if the open circuit voltageupon full charging is increased, the occurrence of the smallshort-circuit is suppressed and the battery characteristics areimproved.

As mentioned above, according to the first embodiment, the secondarybattery has the cathode 21 and the anode 22 arranged so as to face eachother and the separator 23 in between. The open circuit voltage in thefull charging state per pair of cathode 21 and anode 22 lies within arange from 4.25V or more to 4.60V or less or a range from 4.35V or moreto 4.60V or less, the separator 23 has the film thickness of 10 to 20μm, the converted piercing strength of the separator 23 is equal to 300gf or more in which the piercing strength is converted to the piercingstrength which will be obtained in case the film thickness is equal to20 μm (or equal to 150 gf or more in which the piercing strength isconverted to the piercing strength which will be obtained in case whenthe film thickness is equal to 10 μm), and the air permeability of thebase material layer 23A is equal to or larger than 10% of that of thewhole separator. Therefore, the safety at the time of the externalshort-circuit or the like can be improved without causing adeterioration in the load characteristics.

As mentioned above, the secondary battery has the cathode 21 and theanode 22 arranged so as to face each other and the separator 23 inbetween. The open circuit voltage in the full charging state per pair ofcathode 21 and anode 22 lies within a range from 4.25V or more to 4.60Vor less or a range from 4.35V or more to 4.60V or less, the separator 23has the film thickness of 10 to 20 the converted piercing strength ofthe separator 23 is equal to 300 gf or less in which the piercingstrength is converted to the piercing strength which will be obtained incase the film thickness is equal to 20 μm (or equal to 150 gf or less inwhich the piercing strength is converted to the piercing strength whichwill be obtained in case when the film thickness is equal to 10 μm), andthe air permeability of the base material layer 23A is equal to orlarger than 35% of that of the whole separator. Therefore, the safety atthe time of the external short-circuit or the like can be improvedwithout causing a deterioration in the load characteristics.

Since the open circuit voltage in the full charging state lies within arange from 4.25V or more to 4.60V or less or a range from 4.35V or moreto 4.60V or less, the high energy density can be obtained. The layermade of at least one kind selected from the group includingpolyvinylidene fluoride, polyethylene terephthalate, polypropylene, andaramid is formed on the side of the separator 23 which faces at leastthe cathode 21. Thus, the chemical stability of the separator 23 can beimproved and the occurrence of the small short-circuit is suppressed.Thus, the energy density can be raised and the battery characteristicssuch as cycle characteristics, high-temperature holding characteristics,or the like can be improved.

The relation between the measured piercing strength and the convertedpiercing strength is as follows.S ₂₀ =S×20/T,S ₁₀ =S×10/T,S ₂₀ =S ₁₀×2,

wherein, S₂₀ is the converted piercing strength converted into thepiercing strength which will be obtained in case the film thickness is20 μm, S₁₀ is the converted piercing strength converted into thepiercing strength which will be obtained in case the film thickness is10 μm, S is the measured piercing strength, T is the film thickness.

(2) Second Embodiment

A secondary battery according to the second embodiment is a lithiummetal secondary battery in which the capacitance of the anode isexpressed by a capacitive component by precipitation and dissolution oflithium as an electrode reactive substance.

This secondary battery has a construction and an effect similar to thoseof the secondary battery of the first embodiment except that aconstruction of the anode active material layer 22B differs from that inthe first embodiment. Therefore, the corresponding component elements inFIGS. 1 and 2 are designated by the same reference numerals and anexplanation of the same portions is omitted here.

The anode active material layer 22B is made of a lithium metal as ananode active material and can obtain the high energy density. Althoughit is possible to construct in such a manner that the battery alreadyhas the anode active material layer 22B upon assembling, it is alsopossible to construct in such a manner that the anode active materiallayer 22B does not exist upon assembling but it is made of the lithiummetal which has been precipitated upon charging. The anode activematerial layer 22B can be also used as a collector and the anodecollector 22A can be deleted.

This secondary battery can be manufactured in a manner similar to thesecondary battery according to the first embodiment except that theanode 22 is formed only by the anode collector 22A or only by thelithium metal or the anode active material layer 22B is formed byadhering the lithium metal to the anode collector 22A.

In this secondary battery, when the charge is performed, for example,lithium ions are dedoped from the cathode 21 and precipitated as alithium metal on the surface of the anode collector 22A through theelectrolyte, thereby forming the anode active material layer 22B asshown in FIG. 2. When the discharge is performed, for example, thelithium metal is eluted as lithium ions from the anode active materiallayer 22B and doped into the cathode 21 through the electrolyte. Sincethe separator 23 has the foregoing construction here, the chemicalstability is improved and even if the open circuit voltage upon fullcharging is raised, the occurrence of the small short-circuit issuppressed and the battery characteristics are improved.

(3) Third Embodiment

In a secondary battery according to the third embodiment, a capacitanceof an anode includes a capacitive component by the dope and dedope oflithium as an electrode reactive substance and a capacitive component bythe precipitation and dissolution of lithium and is expressed by the sumof them.

This secondary battery has a construction and an effect similar to thoseof the secondary battery of the first or second embodiment except that aconstruction of the anode active material layer differs from that in thefirst or second embodiment, and it can be similarly manufactured.Therefore, the corresponding component elements in FIGS. 1 and 2 aredesignated by the same reference numerals and will be explained. Adetailed explanation of the same portions is omitted here.

In the anode active material layer 22B, for example, the chargecapacitance of the anode material which can dope and dedope lithium isset to be smaller than that of the cathode 21, so that the precipitationof the lithium metal in the anode 22 is started at a point of time whenthe open circuit voltage (that is, battery voltage) is lower than anovercharge voltage in the charging step. Consequently, in this secondarybattery, both of the anode material which can dope and dedope lithiumand the lithium metal function as an anode active material, while theanode material which can dope and dedope lithium becomes a base materialwhen the lithium metal is precipitated.

The overcharge voltage denotes an open circuit voltage when the batteryenters the overcharging state and indicates a voltage higher than anopen circuit voltage of a “fully charged” battery disclosed and definedin, for example, “Lithium secondary battery safety evaluation referenceguideline” (SBA G1101) as one of the guides determined by BatteryIndustry Association in Japan. In other words, the overcharge voltageindicates a voltage higher than the open circuit voltage after thebattery was charged by using a charging method used when a nominalcapacitance of each battery is obtained, a standard charging method, ora recommended charging method.

This secondary battery is similar to the lithium ion secondary batteryin the related art with respect to a point that the anode material whichcan dope and dedope lithium is used for the anode 22 and is also similarto the lithium metal secondary battery in the related art with respectto a point that the lithium metal is precipitated in the anode 22.However, since the lithium metal is precipitated in the anode materialwhich can dope and dedope lithium, the high energy density can beobtained and the cycle characteristics and rapid chargingcharacteristics can be improved.

In this secondary battery, when the charge is performed, lithium ionsare dedoped from the cathode 21 and are first doped into the anodematerial which can dope and dedope lithium contained in the anode 22through the electrolyte. When the charge is further continued, in thestate where the open circuit voltage is lower than the overchargevoltage, the precipitation of the lithium metal on the surface of theanode material which can dope and dedope lithium is started. After that,the lithium metal continues to be precipitated in the anode 22 until thecharge is finished. Subsequently, when the discharge is performed,first, the lithium metal precipitated in the anode 22 is eluted aslithium ions and doped into the cathode 21 through the electrolyte. Whenthe discharge is further continued, the lithium ions doped in the anodematerial which can dope and dedope lithium in the anode 22 are dedopedand doped into the cathode 21 through the electrolyte. Since theseparator 23 has the foregoing construction here, the chemical stabilityis improved and even if the open circuit voltage upon full charging israised, the occurrence of the small short-circuit is suppressed and thebattery characteristics are improved.

(4) Fourth Embodiment

FIG. 3 is an exploded perspective view showing an example of aconstruction of a secondary battery according to the fourth embodiment.According to this secondary battery, a winded electrode member 30 towhich a cathode lead 31 and an anode lead 32 have been attached isenclosed in a film-shaped sheathing member 40, and miniaturization, alight weight, and a thin shape can be realized.

Each of the cathode lead 31 and the anode lead 32 is led out, forexample, in the same direction from the inside of the sheathing member40 toward the outside. For example, each of the cathode lead 31 and theanode lead 32 is made of a metal material such as aluminum, copper,nickel, stainless steel, or the like and has a thin-plate shape or amesh shape.

The sheathing member 40 is made of a rectangular aluminum laminate filmobtained by, for example, adhering a nylon film, an aluminum foil, and apolyethylene film in this order. The sheathing member 40 is arranged sothat, for example, the polyethylene film side and the winded electrodemember 30 face each other and their outer edge portions are closelyadhered by melt-bonding or by an adhesive agent. Adhesive films 41 toprevent an intrusion of the open air are inserted between the sheathingmember 40, the cathode lead 31, and the anode lead 32. The adhesivefilms 41 are made of a material having adhesive performance to thecathode lead 31 and the anode lead 32, for example, a polyolefin resinsuch as polyethylene, polypropylene, denatured polyethylene, denaturedpolypropylene, or the like.

The sheathing member 40 may be constructed by a laminate film havinganother structure, a high molecular film made of polypropylene or thelike, or a metal film in place of the foregoing aluminum laminate film.

FIG. 4 shows a cross sectional structure taken along the I-I line in thewinded electrode member 30 shown in FIG. 3. The winded electrode member30 is constructed in such a manner that a cathode 33 and an anode 34 arelaminated through a separator 35 and an electrolyte layer 36 and woundand the outermost peripheral portion is protected by a protecting tape37.

The cathode 33 has a structure in which a cathode active material layer33B or cathode active material layers 33B is/are provided for onesurface or both surfaces of a cathode collector 33A. The anode 34 has astructure in which an anode active material layer 34B or anode activematerial layers 34B is/are provided for one surface or both surfaces ofan anode collector 34A. The cathode 33 and the anode 34 are arranged sothat the cathode active material layer 33B and the anode active materiallayer 34B face each other. A construction of the cathode collector 33A,cathode active material layer 33B, anode collector 34A, anode activematerial layer 34B, and separator 35 is similar to that of the cathodecollector 21A, cathode active material layer 21B, anode collector 22A,anode active material layer 22B, and separator 23 described in each ofthe first to third embodiments.

The electrolyte layer 36 includes an electrolytic solution and a highmolecular compound serving as a holder to hold the electrolytic solutionand is in what is called a gel-state. The gel-like electrolyte layer 36is preferable because high ion conductivity can be obtained and aleakage of the solution of the battery can be prevented. A constructionof the electrolytic solution (that is, solvent, electrolytic salt, orthe like) is similar to that of the secondary battery according to eachof the first to third embodiments. As a high molecular compound, forexample, there can be mentioned: polyacrylonitrile; polyvinylidenefluoride; copolymer of vinylidene fluoride and hexafluoro propylene;polytetrafluoro ethylene; polyhexafluoro propylene; polyethylene oxide;polypropylene oxide; polyphosphazene; polysiloxane; polyvinyl acetate;polyvinyl alcohol; polymethyl methacrylate; polyacrylic acid;polymethacrylate; styrene-butadiene rubber; nitrile-butadiene rubber;polystyrene; polycarbonate; or the like. Polyacrylonitrile,polyvinylidene fluoride, polyhexafluoro propylene, or polyethylene oxideis preferable, particularly, from a viewpoint of electrochemicalstability.

This secondary battery can be manufactured, for example, as follows.

First, each of the cathode 33 and the anode 34 is coated with apresolvent containing a solvent, electrolytic salt, a high molecularcompound, and a mixed solvent, and the mixed solvent is volatilized,thereby forming the electrolyte layer 36. After that, the cathode lead31 is attached to an end portion of the cathode collector 33A bywelding. The anode lead 32 is also attached to an end portion of theanode collector 34A by welding. Subsequently, the cathode 33 and anode34 on each of which the electrolyte layer 36 has been formed arelaminated through the separator 35, thereby obtaining a laminate. Afterthat, this laminate is wound in its longitudinal direction and theprotecting tape 37 is adhered onto the outermost peripheral portion,thereby forming the winded electrode member 30. Finally, for example,the winded electrode member 30 is sandwiched between the sheathingmembers 40 and the outer edge portions of the sheathing members 40 areclosely adhered by thermal melt-bonding or the like, thereby sealing thewinded electrode member 30. In this instance, the adhesive films 41 areinserted among the cathode lead 31, the anode lead 32, and the sheathingmember 40. Thus, the secondary battery shown in FIGS. 3 and 4 isobtained.

The secondary battery may be manufactured as follows. First, asmentioned above, the cathode 33 and the anode 34 are manufactured, thecathode lead 31 is attached to the cathode 33, the anode lead 32 isattached to the anode 34, thereafter, the cathode 33 and anode 34 arelaminated through the separator 35 and wound, the protecting tape 37 isadhered onto the outermost peripheral portion, thereby forming a windedelement as a precursor of the winded electrode member 30. Subsequently,the winded element is sandwiched between the sheathing members 40, theouter edge portions excluding one side is thermally melt-bonded into abag-shaped, and the winded electrode member 30 is enclosed in thesheathing members 40. Subsequently, a composition for the electrolytecontaining a solvent, electrolytic salt, a monomer as a raw material ofthe high molecular compound, a polymerization initiator, and anothermaterial such as a polymerization inhibitor or the like as necessary isprepared and injected into the sheathing members 40.

After the composition for the electrolyte was injected, an openingportion of the sheathing members 40 is thermally melt-bonded under thevacuum atmosphere, thereby sealing the winded electrode member 30.Subsequently, the monomer is polymerized by applying heat so as to forma high molecular compound, thereby forming the gel-like electrolytelayer 36. In this manner, the secondary battery shown in FIG. 3 isobtained.

Functions and effects of this secondary battery are similar to those ofthe secondary batteries according to the first to third embodiments.

A manufacturing method of the battery in which the capacitance of theanode 22 is expressed by the capacitive component by the dope and dedopeof lithium, that is, the lithium ion secondary battery will be describedhereinbelow with reference to FIG. 1.

First, the cathode active material is formed. Commercially availablenickel nitrate, cobalt nitrate, and manganese nitrate are mixed as anaqueous solution so that mole ratios of Ni, Co, and Mn are respectivelyequal to 0.50, 0.20, and 0.30 and, thereafter, aqueous ammonia isdropped into the mixture solution while sufficiently agitating them, sothat a composite hydroxide is obtained. The composite hydroxide and alithium hydroxide are mixed, baked at 900° C. for 10 hours by using anelectric furnace, and thereafter ground, so that lithium composite oxidepowder as a cathode active material is obtained. By analyzing theobtained lithium composite oxide powder by ASS (Atomic AbsorptionSpectrometry), the compositions of LiNi_(0.50)Co_(0.20)Mn_(0.30)O₂ areconfirmed. By measuring particle size by a laser diffracting method, anaverage particle size is equal to 13 μm. By further performing an X-raydiffraction measurement, it has been confirmed that a measured patternis analogous to a pattern of LiNiO₂ disclosed in “09-0063” of an ICDD(International Center for Diffraction Data) card and a stratifiedrock-salt structure similar to that of LiNiO₂ is formed. Moreover, byobserving the cathode active material by an SEM (Scanning ElectronMicroscope), spherical particles in which primary particles of 0.1 to 5μm have been aggregated are observed.

The obtained LiNi_(0.50)Co_(0.20)Mn_(0.30)O₂ powder, graphite as aconductive material, and polyvinylidene fluoride as a binder are mixedat mass ratios of (LiNi_(0.50)Co_(0.20)Mn_(0.30)O₂ powder: graphite:polyvinylidene fluoride=86:10:4) and the cathode mixture is adjusted.Subsequently, the cathode mixture is dispersed intoN-methyl-2-pyrolidone as a solvent, thereby forming the cathode mixtureslurry. Subsequently, both surfaces of the cathode collector 21A made ofa belt-shaped aluminum foil having a thickness of 20 μm are uniformlycoated with the cathode mixture slurry, the solvent is dried,thereafter, the collector is compression-molded by the roll pressingmachine, and the cathode active material layer 21B is formed. Thus, thecathode 21 is manufactured. A thickness of cathode 21 is set to 150 μm.After that, the cathode lead 25 made of aluminum is attached to one endof the cathode collector 21A.

As an anode active material, spherical graphite powder whose averageparticle size is equal to 30 μm and polyvinylidene fluoride as a binderare mixed at a mass ratio of (spherical graphite powder:polyvinylidenefluoride=90:10) and the anode mixture is adjusted. Subsequently, theanode mixture is dispersed into N-methyl-2-pyrolidone as a solvent,thereby forming the anode mixture slurry. Subsequently, both surfaces ofthe anode collector 22A made of a belt-shaped copper foil having athickness of 15 μm are uniformly coated with the anode mixture slurry,the collector is press-molded with heat, and the anode active materiallayer 22B is formed. Thus, the anode 22 is manufactured. A thickness ofanode 22 is set to 160 μm. After that, the anode lead 26 made of nickelis attached to one end of the anode collector 22A. An electrochemicalequivalent ratio of the cathode 21 and the anode 22 is designed so thatthe capacitance of the anode 22 is expressed by the capacitive componentby the dope and dedope of lithium.

After the cathode 21 and the anode 22 were formed as mentioned above,the separator 23 serving as a microporous membrane having theconstruction shown in each of TABLEs 1 to 8 is prepared. The anode 22,separator 23, cathode 21, and separator 23 are laminated in this orderand the laminated body is wound in a spiral shape a number of times,thereby forming the winded electrode member 20 of a jelly-roll type. Asseparators 23, as shown in TABLEs 1 to 8, the separator obtained bythermally melt-bonding the polypropylene surface layer 23B onto bothsurfaces of the polyethylene base material layer 23A and the separatorformed only by the polyethylene base material layer 23A are used. Thefilm thickness is set to the following eight kinds of values: 5 μm, 10μm, 12 μm, 16 μm, 18 μm, 20 μm, 30 μm, and 35 μm.

After the winded electrode member 20 was manufactured, the windedelectrode member 20 is sandwiched by a pair of insulating plates 12 and13, the anode lead 26 is welded to the battery can 11, the cathode lead25 is welded to the relief valve mechanism 15, and the winded electrodemember 20 is enclosed in the battery can 11 made of nickel-plated iron.After that, an electrolytic solution of 4.0 g is injected into thebattery can 11 by a pressure reducing system.

As an electrolytic solution, there is used an electrolytic solutionobtained by dissolving LiPF₆ as an electrolyte salt of 1.5 mol/kg intothe solvent obtained by mixing ethylene carbonate, dimethyl carbonate,and vinylene carbonate as a solvent at mass ratios of (ethylenecarbonate: dimethyl carbonate: vinylene carbonate=35:60:1).

After the electrolytic solution was injected into the battery can 11,the battery cap 14 is caulked to the battery can 11 through the gasket17 whose surface has been coated with asphalt, so that the cylindricalsecondary batteries each having a diameter of 18 mm and a height of 65mm of the samples 1-1-1 to 1-8-12 are obtained.

<External Short-Circuit Test>

Each of the secondary batteries obtained as mentioned above is chargedat a constant current of 1000 mA and a constant voltage of 4.2V. Afterthat, an external short-circuit test is executed in a high-temperaturebath at 60° C. and the temperature of the center part of the batteryafter 5 second interval from the short-cut is measured. By this test,when the battery temperature does not exceed 120° C., cut-off due to theshut-down of the separator 23 can be performed and the PTC element 16 isunnecessary. However, when the battery temperature exceeds 120° C., theshut-down by the separator 23 is not performed and the PTC element 16 iscertainly necessary. In other words, the secondary battery in which thecut-off can be performed by the shut-down of the separator 23 even ifthere is no PTC element 16 can be regarded as a cell having excellentsafety.

<Load Characteristics Evaluation>

First, each of the secondary batteries obtained as mentioned above ischarged at a constant current of 1000 mA and a constant voltage of 4.2Vunder an environment of 23° C. After that, each of the secondarybatteries is constant-current discharged under the conditions of acurrent of 0.2 C and a final voltage of 3V. Subsequently, theconstant-current and constant-voltage charge is executed at 1000 mA and4.2V. After that, the constant-current discharge is executed under theconditions of a current of 1 C and a final voltage of 3V.

After that, the load characteristics are obtained by the followingexpression.[(discharge capacitance (mAh) at current 1 C)/(discharge capacitance(mAh) at current 0.2 C)]×100

where, the discharge capacitance is obtained by the followingexpression.(Current value)×(discharge time until final voltage of 3.0V)

1 C: current value adapted to discharge a rated capacitance of thebattery for 1 hour

0.2 C: current value adapted to discharge the rated capacitance of thebattery for 5 hours

Results of the external short-circuit test and the load characteristicsevaluation of the foregoing Samples 1-1-1 to 6-8-12 are shown in TABLEs1 to 48. The following points are understood from the evaluationresults.

When the film thickness of the separator is less than 10 μm, althoughthe load characteristics are good, the PTC element 16 is necessary atall of the charge voltages.

When the film thickness of the separator exceeds 20 μm, although the PTCelement 16 is not necessary at all of the charge voltages, the loadcharacteristics are bad.

The secondary battery in which the PTC element 16 is unnecessary and theload characteristics exceed 95% is a secondary battery using theseparator 23 which has a film thickness of 10 to 20 μm and in which apiercing strength in the case of the film thickness of 20 μm is equal to300 gf (150 gf in the case of the film thickness of 10 μm) or more andair permeability of the polyethylene base material layer 23A is equal toor larger than 10% of that of the whole separator and is a secondarybattery using the separator 23 in which the piercing strength is equalto or less than 300 gf and the air permeability of the polyethylene basematerial layer 23A is equal to or larger than 35% of that of the wholeseparator.

As shown in table 1-48, the layers with same thickness and same voidratio do not always take on the same air permeability. The permeabilitycan be different. And the necessity of PTC element checked by theexternal short-circuit test at 60° C. depends not on thickness or voidratio of the polyethylene base material layer 23A, but on airpermeability.

Although examples of embodiments have specifically been described above,the embodiments are not limited to them but many modifications arepossible.

For example, the numerical values mentioned in the foregoing embodimentsand Examples are merely shown as examples and other numerical valuesdifferent from them may be used as necessary.

For example, although the foregoing embodiments and Examples have beenexplained with respect to the case of using lithium as an electrodereactive substance, the invention can be also applied and similareffects can be obtained with respect to the case of using another 1Agroup element such as sodium (Na), potassium (K), or the like, a 2Agroup element such as magnesium, calcium (Ca), or the like, anotherlight metal such as aluminum or the like, lithium, or their alloy. Inthis instance, an anode material as described in the foregoingembodiments can be similarly used as an anode active material.

Although the foregoing examples have been explained with respect to thesecondary battery having a winded structure, other battery structurescan be similarly applied such as a battery having a structure in whichthe cathode and anode are folded or piled. In addition, the secondarybattery can be what is called a coin type, a button type, a rectangulartype, or the like.
